Application filed July 17, 1912. Serial No. 709,855.

To all 107mm it may concern:

lie it known that We, WAnum: C. Rims, of

Somerville, in the county of Middlesex and ate of Iliassachusctts, and S'razvnnv ETH- ixo'ro'x, of lVinthrop, county of Suffolk, d said State, citizens of the United States, ave invented new and useful Improvements in Sanitary VVater-Closets, of which the following is a specification.

".lhis invention relates to sanitary water closets. and itsobject is to provide an automatic mechanism for laying a fresh paper covering over the seat previous to use by each successive occupant.

in the preferred form of our device we use a iuodificaiimi of that type of seat known as.

the horseshoe having two separate straight sides, and being open both in front and in back, whereas the horseshoe is open only in front, the paper being supplied to each of these sides from separate rolls by separate feeding mechanisms, both however actuated by the same operating mechanism. Thus no perforation is necessary and ordinary rolls of paper may be employed just as they come from the mill without special preparation. An added advantage arising from use of the double instead of the single sheet of paper is that each section of the paper covers a smaller area of the seat, and thus may be more firmly held with less danger of displacement or injury. We do not limit ourselves, however, to the use of this particular form of seat, as our improved mechanism is adapted to be combined with any other type having not only sides, but front or back, or both.

A. radically novel feature is theemployment of a barrier for preventing use of the seat without prepayment. This barrier consists of a pivoted skeleton frame, carrying a series of curved bars norn'ially extending over the seat in such a manner as to obstruct its use, in which position the barrier is locked until released by the deposit of a coin in a slot. .Vhen thus released the barrier may be swung down under the seat and out H of the way of the occupant.

Fig. 3 is a side elevation showing the casing partially broken away. Fig. 4 we vertical section on line 44 of Fig. 1. Fig. 5 1s a horizontal section of a portion of the left side paper supply mechanism. Fig. 6 1:; a horizontal section of a portion of the right side paper supply mechanism. Fig. 7 is a side elevation of a portion of the left s de paper supply mechanism. Fig. 8 is a side elevation of a portion of the right side paper supply mechanism. Fig. 9 is a vertical section on line 9-9 of the barrier depressed and locked. a detail elevation of the latch-36.

,Referring to the drawing, the bowl represented by the numeral 1.

1 is the casing inclosing the mechanism, which may be secured to the bowl in any suitable manner. This casing also serves as a support for the various bearing mountings. 18 is the seat composed of the sides 17 and 30, and superstructure sides 37 and 38.

9 is the barrier composed of the curved Fig. 1, showing Fig. 10 is bars 2* and 2 quadrants 3 and 4, radial. .arms 5 and the cross bar 6. The barrier also serves as the main actuating lever for operating the mechanism. The upper ends of the curved bars 2 extend into the coin boX 7, which is the device for locking the barrier in the position shown in Fig. 1, until released by the deposit of a coin in the slot 8, in the coin box '7. Any one of several well known coin box constructions may be used, which is adapted to release the lever 7 when a coin is deposited in the box 7. The lever 7 engages with slots 7* in the ends of the curved bars 2 9 represents guide collars which support the curved bars 2* of the barrier, which is pivoted at 10.

11 is a rack formed on the quadrant 3, which engages, during the first part of the downward movement of the barrier, the gear 153, which. through the intermediate gea s 13 and 14, operates to advance the plunger 15, which draws the fresh section of paper from the reservoir spindle 16 over the side 17 of the seat 18.

The here] gear 13 meshes with the bevel gear 14, fast to the shaft 46, and r0- tates the shaft; 46. This rotates gears 47 and 48, last to the shat't 16, which gears engage respectively racks 49 and 50 attached to the und r side of the phinger 15. The plunger is thus advanced and a section of paper twice the width of the 'ilunger is drawn from the reservoir spindle 113 over the side 37 of the superstructure of the seat 18. While the plunger is being advanced all possibility that used paper will he drawn out from the take-up spindle 23 is prevented by the pawl 51 which engages a ratchet )1} on the spindle and prevents unwinding rotation. ,V'lien the plunger 15 has reached its most advanced position, the rack 11 ceases to engage the ear 12, and further advancing rotation of the'shai't it; consequently ceases. At the same moment the rack it) engages the gear 20, thus rotating, by means oi the pawl 90 fast to the gear and the ratchet 91 fast to the sleeve 52, the hovel gear 21 also last to the sleeve 52. The hevel gear 21 meshes with the bevel gear 22, last to the shaft 10, and thus a rotary motion is again imparted to the shaft 4-6, but in the reverse direction; This reverse rotation of the shalt 46 through the gears -17 and 48 and racks 1H and operates to withdraw the plunger 15, during which operation the slack section of used paper is taken up by the rotation. of the spindle 23 actuated by a multiplying chain driven gear consisting of the s n-er-kct 53 loose on shaft 416, but ro tated during the reverse rotation of sha'l't it by the pawl :34, fast. to the sprocket 53 and ratchet 5o, fast to the shaft. 46, the sprocket 56, tast to the sleeve 82, theeup spring 83 and the sprocket chain 57-. in the same manner fresh paper is drawn overthe opposite side' SS ol the su 'ierstructure oi the seat. As the barrier is depressed the rack 2i en- -gages the gear 25, thus rotating, by means oi' the pawl 92 last; to the gear 25 and the ratchet 93 fast; to the shaft the hcvel gear 2 also last to the shaft 58. The bevel gear :20 meshes with the bevel gear 27, fast to the shaft 5 and rotates the shaft 59. This rotates gears i and 31. fast to shaft 59, which gears engage respectively racks ,(32 and (33 attached to the under side of the plunger The plunger thus advanced and a section of paper twice the width of the plunger is drawn from the reservoir spindle 2!) over the side 38 oi the superstructure of the seat While the plunger is being advaun all'pe. iilitv that used paper will he drawn from the take-up spindle iges a ratchet F)? on the spindle -l5 and prevents unwinding rotatuui. When the is preuented bv the pawl 34; which eni I and thus the l l l l j l l l l l i l l plunger 28 has reached its most advanced position, the rack 24 ceases to engage the gear 25 and further advancing rotation of the shaft 59 consequently ceases. At. the same moment the rack 31 engages the gear -32, thus rotating, by means of the pawl Oat last to the gear 32 and the ratchet 95 fast to the sleeve (35, the bevel gear 33, also fast to the sleeve 35. The hevel gear meshes with the bevel gear 34-, fast: to the shaft 59 and thus a rotary motion is again imparted to the shaft, 55), but in the reverse direction. This reverse rotation of the shaft 59 through the gears 60 and ($1 and racks G2 and 63, operates to withdraw the plunger 28 during which operation the slack section of used paper is taken up by the rotation of the spindle 35, actuated by a multiplying chain driven gear consisting of the sprocket (i6. loose on shaft 59, hut rotated during the reverse rotation of shaft 59 by t pawl 67, fast to the sprocket (36 and ratchet 68 fast to the shaft 5.), the sprocket GED-fast to the sleeve 9 l, the cup spring 85 and the sprocket chain U. As the harrier lllJPlOtlCllGS the extreme point of depression the projection 7-t on, the quadrant lis brought into contact with the hell crank lever 75, the lever is thrown 'ithdraWing the pitman 76 from contact wif the hut-t 77 of the pawl 72, and the pawl is forced by the spring 72 into engagement with the rack '73. At, the same time the clamping fingers 80 and 81 fold the edges of the paper over the beveled front edges 86 and 87 of the sides 17 and 30 re spectively of the seat 18. rear-hes the extreme point of depression it is caught and locked ashefore stated by thelatch 36. The eperationof this latch is as l'ollowsz-As the barrier approaches the extrenie point of depression, the pin 98 comes into contact with the latch 36, which is rigidly secured to the pivot shaft ofthe superstructure 38 at 38 at a slight angle. to the line of direction of motion of the pin, andl'm'ces the point of depression is reached, at which point the pin 98 falls into the recess 36 at the base of the latch 36. Actuated by the s 'iriug-jttl, the latch now returns to its normal position and the harrier is thus firmly locked until released by the weight of the occupant upon the superstructure 38. It is As the barrier" latch aside until the extremedesirable but; not essential that a latch of like manner on the opposite side of the tie vice as shown in Fig. 1.1 The seat is now ready for use. The weight of the occilpant brings sullicient. pressure to hear upon the sides 37 and 38 of the superstructure 0f the seat 18 so that the springs 39 andAO are compressed, the superstructure is depressed, latch 36 is tripped, releasing the barrier which is now held down by the legs ofthe'occupant resting over the cross bar 6. As the occupa nt rises, the barrier, actuated by the sprin s71 and 71 returns to its position above-t e seat. During this return movement depression of -the barrier is prevented at all oints by the pawl 72 in engagement with t e rack 73 its the barrier reaches its extreme high. point, the prosection 78cm the quadrant 4 is brought into contact with the bell crank lever 75, the lever, is thrown thus actuating the iitman which is brought into contact with to butt 7 7 throwing the pawl'72 out of engagement with the rack 73, in which position the pawl is held. by the spring 7 9, Coincidentalh the barrier is automatically locked and the device can now be operated only upon deposit of another coin.
